I'm guessing the worst part with AS is trying to get one.
We researched for several weeks. Living in the northeast our convenient choices were in NJ,NH,NY. Nothing in our state which is fine. We worked with a really informative sales person to become educated.

So finally we pulled the trigger in August. We were told we would see it mid October now mid November. I get it... from what I hear they're in big demand.

But once I mailed the down payment its been crickets.... no updates, slow response to emails, no return phone calls. I mean really these AS are $$$

Sounds like you might have a problem with a specific dealership not with Airstream. If you have given up on the dealership doing the right thing you could contact Airstream directly. Pretty sure they like to hear of such possible poor customer service on the part of their dealerships. Good luck. Hope it all works out to your satisfaction.
* There is almost always two sides to every story. We usually only hear one side here.
* I believe it is normal to take 4 to 6 months for delivery of a custom ordered Airstream.

I had no dealer problems but being an impatient person I called customer service at AS for an update, they were extremely helpful even supplying me with the build week of my trailer. Suggest you do that, they will email you the info you desire.
That dealer you purchased from needs a wake up call on how to treat a new customer, good luck & the agrevation will be worth it.

Ordered ours mid Aug., picked it up on Saturday. We were told it would take about 6-8 weeks, we were at about 10.

I called and called and called. The salesman even said when we were picking up something to the effect of " missing my daily phone calls". In truth, I had 3 questions throughout the course of our wait. He only called me back once, so I called everyday until I got an answer. I was never upset or short with anyone, I was persistent. I was slightly disappointed by this, but overall very happy with my experience.

It might just be the way dealerships handle it, but I would say not to let yourself be ignored. You have a right to know. I was told the week after I put my money down when it was scheduled to come off the line.

After the WV AS Rally, last June/July, we toured the AS factory, in Ohio. While there, I asked the tour guide how they schedule their AS manufacture. He was quite clear --- they do not make a full line of trailers at once. Rather, they gather all their orders for all types of their trailers, and upon some criterion that he didn't mention, they would then select one type & make a batch of them. When that run was done, they would select another type & make a batch of that type. One apparent consequence of this is that if you order trailer type x and it's the only one of that type then ordered on the factory's books, you are going to wait a long time until the factory accumulates more of those orders before your trailer is made. He also said that the 25 was the most popular trailer they make, so I would guess that on average, the wait for a 25 after it is ordered is likely the shortest. If the above is true, then it would seem as if an AS dealer has little ability to control the wait time for an ordered AS. I also asked the guide if they will make custom trailers --- customized as desired by a buyer, & he responded "No," that they had a very limited number of variations available within any particular type of AS, and those variations (eg, extra awnings, extra air conditioner, solar power, etc.) were the only variations they offered, period, no exceptions. Customization was available by after-market dealers, but not by the AS factory itself. At least, the foregoing was I got from this tour guide. Maybe other's experience is different.

We ordered our 2017 Classic in late April and picked it up late June. It was delayed 3 weeks due to the new Alde hot water and heat system. Our dealer was very responsive with keeping us updated and pushing on AS to get it done. We were leaving on a 6 week trip July 1 and really wanted some time with our new classic before heading out. It was stressful that it was delayed but our dealer, Windish RV in Lakewood CO, was awesome about communicating with us.

We love our AS and it was worth the wait. Sorry your having issues and I would reach out to AS directly if you continue to be ignored by your dealer.
